Is your screen any better? Please post a shot similar to mine, taken at an angle where only one picture should be visible. I'd like to see if the quality of the display differs from 3DS to 3DS. Also turn up 3D to the maximum as well.
Also, if you are interested, here's a recoding of my display's "3D quality": http://oehr.evoboxes.net/Nintendo3DS.mp4

 

Ghosting disappears if you play with higher brightness, or in a place where light won't relect off your 3DS.
Also in OoT you see ghosting in really dark areas like caves or the exits of the lost woods
and taking a screen shot like that doesn't help since you can't capture 3d on a normal camera.

 

Can't take pictures right now but I have the same problem too. And it's mostly in the places that Sonic mentioned above.

 

Can't say I've ever really noticed this, but I never play on full brightness (hurts my eyes) only ever about 2 or 3.

Perhaps that's the only solution?

 

Quality is quite poor as it's from an iPod touch (in poor lighting) but hopefully you can see that there's no ghosting, even though it's at pretty much the exact same angle.



The brightness is at 2.

 

I found ghosting to be very intensive and annoying in Rayman 3D what led me to the conclusion that it might not be only darkness responsible for ghosting.

 

these are three very different technologies.
you watch movies in the cinema in 3d using two projectors, having the polarized glasses each filter one projection. due to diffusion of the light and lower quality of the polarized glass (, you might end up with a ghost image.
on a TV or monitor, you have a framerate of around 120, switching every frame to the other eyes point of view. the shutter glasses will switch from transparent to black just as fast, leaving your eye with an after image. 2 frames result into a 3D picture. with a good monitor and proper glasses, there should be minimal to no ghosting.
on a 3DS (or those new 3D smartphones), you have 2 images, while each can only be seen by one eye at a time, if your head is in the right spot. similar to lenticular printing using regular LCD technology (setup is different though, check Autostereoscopy on wikipedia). obviously, you can see the other eye's image and you are very limited when it comes to the viewpoints and distance. Additionally, if you're unlucky, you get a crappy display like the one thats apparently built into every nintendo 3ds and get ghosting wherever your head is...

beside that, the most successful, ghosting free (fake) 3D technology out there is headtracking. When the device knows where you are, the correct image can be shown, which will only look for the one whos head is being tracked. Unfortunately this is limited to only one person at a time, thus, not practical for mass production/deployment. plus only possible with computer generated graphics, not movies

 

I've never seen a dual projector 3D setup in a theater. Regardless of the tech used, 3D in general suffers from ghosting mostly in situations where light & dark colors contrast each other.

 

I see ghosting when I'm too close to my 3DS (as the manual says, stay about 14in away from the screen) but this rarely happens. But for OoT they really did mess up with that game, ghosting is all over that game no matter what. It was a bad job, not really the 3DS or certain people... they just messed up.
